This exceptional piece is a massive Roman glass bottle that dates circa 2nd century A.D. This piece is approximately 12.1 inches high, and is in flawless condition with no cracks and/or chips. This beautiful piece is a pale blue-green color, is free blown, and has a slightly indented "dimple base". This piece also has a long cylindrical neck that is constricted at the lower end, and has a flanged "roll-band" below the rounded rim. This "roll-band" was designed to act as an aid for a portable seal over the opening, such as an animal skin or textile seal. This large-scale piece was also likely a storage vessel for a precious oil or unguent. This piece has a beautiful multi-colored iridescent patina, exceptional smooth surfaces, and some minute root marking. Large-scale Roman blown glass vessels like this example took a great deal of skill to produce, and large-scale pieces with balanced symmetry like this example are rare on the market. In addition, flawless examples like this piece are also not often seen as well. A rare and exceptional large-scale piece that has an interesting design with a brilliant multi-colored patina.
